10 rall 'whom 'it may concern:

Be it known that we, DAVID MORITZ, of Carmansville, in the county of NewYork and State of New York, and ROBERT WHITE, of Mott Haven, in thecounty of Westchester and State of New York, have invented a new andImproved Book-Holder, of which the followingis a specification:

Figure l represents a vertical longitudinal section of our improvedbook-holder. Fig. 2 is a transverse section on the line c c, Fig. l.Fig. 3 is a longitudinal section ot' a moditication thereof.

Similar letters of reference indicate corresponding parts.

This invention relates to a new strap 7 or holder for books, beingintended for childrens use while carrying their books to and fromschool, and for similar purposes. The

-invention consists in the combination ot a spring slide with aperforated guide and with the fastening-string, all operating in suchmanner that the string drawn through slide and guide will be clasped andheld secured by the action of the spring.

A and B are the two plates o1' pieces of wood or other material betweenwhich the books or things to be secured are placed. O is a string orseries of strings, extending from the lower plate B through holes nearthe ends of the upper plate A and thence through holes in a tubularpost, D, that projects from the plate A. E is a plug or slide fittedinto the tube D, and perforated so that the string O is also drawnthrough it, as shown. A spring, a, of

suitable kind, is placed within the tube D beneath the plug E, elevatingthe latter and until the plates A B are the requisite distance apart.The plug upon being released will at once secure the string in theposition in which it was last left.

Fig. 3 shows a modification of the invention in form of a tubular slide,E, on a solid guide, D, with the spring a above the slide. In this caseonly` the guide D is perforated,the spring crowding the end yot Eagainst the string, as shown, and thereby bending the string. Thistubular slide may as well be under the string with the spring a beneaththe slide.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. The slide E and spring a combined with theperforated guide D and string O, substantially as and for the purposeherein shown and described.

2. The plates A B combined with the subject-matter ot' the foregoingclause.
